Interactions and Interdependence
1. Examine your photograph and make a T-chart. On one side of the chart list all of the biotic (living) things you
see in the picture.
2. Now examine the picture again this time take note of all the a-biotic (non-living) things you see in the photo.
List these on the other side of the T chart.
3. Compare your T-chart with the rest of your groups.
4. As a table group make a diagram or flow chart on notebook paper that shows how the biotic things in your
picture interact.
5. How do the biotic factors depend on the available abiotic factors? Incorporate these into your diagram and
check it with your teacher.
6. When finalized, copy your groups diagram onto a poster sized piece of paper. Each person in the group should
draw on the poster in ONE color and sign their name on the back.
